im installing my gauges and need help regarding my vacuum/boost line hookups. i have a line coming off the nipple on the front of the intake manifold that splits, 1 goes to the fmu, the other to the bov, off of the bov line it splits again and goes to the ss box. i was told not to have any more lines coming from that spot because it could cause me to have low fuel pressure, leading to big problems, now i need another spot to install my boost gauge, any suggestions.

somebody said i could come off the back of the tb, is that line coming off the back of the tb a vac line?

also in the gauge instructions is says install the gauge between the intake manifold and the fuel pressure regulator, but i dont see a line coming off of the FPR? anybody know about this.

thanks.

 

"somebody said i could come off the back of the tb, is that line coming off the back of the tb a vac line?"

The one on the plenum just behind the TB is where I'm planning on getting a boost reading. I should be equal to the plenum pressure. (At least that's what vortec and kinetix said)

 

I ran the boost sensor off the largest vacuum line on the plenum .Its on the passenger of the plenum .The boost gauge reads vacuum and boost
